Last glacial ice‐rafted debris off southwestern Europe: the role of the British–Irish Ice Sheet
Abstract Ice‐rafted debris (IRD) seeded into the ocean from Northern Hemisphere ice sheets is found in ocean cores along the southwestern European margin through the last glacial period. It is known that the origin of this IRD, especially off Iberia, can vary between North America and western Europe...
